A radio communication system includes multiple base stations including a first base station and a second base station, and a mobile station. In one configuration, the color image sensor array includes first and second sets of sensor pixels sensitive to light having different wavelengths. Conductor depth variation is achieved by etching a dielectric layer to different thicknesses. The dispenser may include electronic circuitry to provide reinforcement andor guidance, for its use and may include means for alerting a third party, such as by a 911 call, of its activation.
